Procedure names were unintentionally case-sensitive when read from the database
(but case-insensitive when fetched from the cache).
Note that the DB-part of qualified names is still case-sensitive (for consistency
with other usage in mysql).

Phase 4 (final): Remove associated stored procedures when a database is dropped.

Phase 3: Made qualified names work for functions as well.

into mysql.com:/home/pem/work/mysql-5.0-merge

Had to initialize some fields in lex before parsing an SP read from
mysql.proc.

Phase 2: Make SPs belong to a DB, and use qualified names.
  As a side effect, using USE in an SP is no longer allowed.
  (It just doesn't work otherwise.)

into mysql.com:/home/pem/work/mysql-5.0

SQL SECURITY DEFINER must enforce reduced rights too, not just additional rights.

without proper locking.

Phase 1: Introduced sp_name class, for qualified name support.

"MySQL server does not detect if garbage chara at the end of query"

Allow the parser to see the garbage characters.
Garbage should cause the parser to report an error.

CONVERT3 was removed, it was for test purposes,
and rather harmful.

Made code shorter and more correct
